Clipping with big collars is a huge problem

[Kaelah]

They fix the clipping for hats though, would it be THAT hard to add something for the back of long hairstyles?

No, but it would upset a lot of players who want long styles. We don't have many long ones as it is, so having it force you to hide the length when you wear a particular collar would suck for some people. I already hate that hats hide certain long hair styles.
